Wireless Controller
waits for an outbound request from the LAN/DMZ on one of the defined outgoing ports,
and then opens an incoming port for that specified type of traffic. This can be thought
of as a form of dynamic port forwarding while an application is transmitting data over
the opened outgoing or incoming port(s).
Port triggering application rules are more flexible than static port forwarding that is an
available option when configuring firewall rules. This is because a port triggering rule
does not have to reference a specific LAN IP or IP range. As well ports are not left
open when not in use, thereby providing a level of security that port forwarding does
not offer.

Port triggering is not appropriate for servers on the LA N, since there is a
dependency on the LAN device making an outgoing connection before
incoming ports are opened.
Some applications require that when external devices connect to them, they receive data
on a specific port or range of ports in order to funct ion properly. The controller must
send all incoming data for that application only on the required port or range of ports.
The controller has a list of common applications and games with corresponding
outbound and inbound ports to open. You can also specif y a port triggering rule by
defining the type of traffic (TCP or UDP) and the range of incoming and outgoing ports
to open when enabled.
